Do I need to go to the hospital or even call my ob?

About 10 minutes ago I fell out in my yard, I hit a hole with my foot and twisted and fell on my knee, I never hit my stomach or fell on my stomach etc. jut banged my knee up a bit. I’m 20 weeks pregnant, so would I need to go to the hospital or even call my doctor? I wouldn’t think so but I’m not 100% no cramping, bleeding or stomach pain.
